product description
EFS Energy Drink

Presenting the all-new EFS drink formulations, completely redesigned for 2010. With the latest amino acid technology, superior mineral bioavailability and the addition of Malic Acid, the new EFS drinks provide EVERYTHING you need to maximize endurance and performance during exercise. You’ll notice the difference right away too. The new formulas are incredibly fine, mix instantly and refuel working muscles faster than ever before. And with the highest electrolyte content available (1160mg of all 5 electrolytes/serving), there’s no need to carry those extra electrolyte pills or add anything else to EFS drinks. You can train and race with confidence knowing you don't have to worry about cramping or dehydration. Times have changed.

THE HIGHEST ELECTROLYTE CONTENT AVAILABLE Clinical research shows endurance athletes require much higher levels of electrolytes than most sports drinks provide to prevent cramping and dehydration (4). The new EFS drinks now contains over 1,160mg of all 5 electrolytes per serving, more than any electrolyte drink on the market.

THE LATEST AMINO ACID TECHNOLOGY The Amino Acids in the EFS drinks are AjiPure amino acids, the purest, most- bioavailable source of free-form amino acids available. AjiPure amino acids have purity levels of 99%-100%. This results in faster and more complete absorption.

SUPERIOR CALCIUM BIOAVALIBILITY The new EFS formulas utilize two unique sources of calcium and magnesium. DiCalcium malate and Dimagnesium malate have superior bioavailability compared to other mineral sources. In a bioavailability study, absorption rates were between 20% and 100% higher using DiCalcium and DiMagnesium malates (1).

NOW WITH MALIC ACID The new EFS drink contains 700mg of Malic Acid, which was not found in the previous formula. Malic acid stimulates oxygen consumption by increasing mitochondrial uptake, improving mitochondrial respiration and increasing energy production. Malic acid is essential in the formation of ATP, the body's energy source. Malic acid allows the body to make ATP more efficiently, even under low oxygen, or hypoxic conditions.

    Great Taste and Easy on the Stomach
    July 24, 2017
    It's hard to find an electrolyte drink that tastes good, isn't too sweet, and doesn't contain maltodextrin. First Endurance Electrolyte Drink has it all!

    I use this for long races
    July 16, 2017
    A great product, tastes well. I mix this with the First Endurance Pre-Race Powder, and drink before workouts. I also drink it during long rides or races and feel this has really helped me, since I do sweat a lot. I have the Lemon-Lime and the Grape. I prefer the Grape over the two, can't comment on the other flavors yet.

    Great Taste
    February 1, 2017
    This is a great tasting energy/fueling drink. I've tried several others, and this is my favorite with no gut aches. I add more scoops for longer distance.
    Great Taste that I don't get tired of.
    Sometime it doesn't mix up/dissolve completely

    My go to for hard sessions and racing
    July 8, 2015
    I've been using EFS electrolyte drink for 3 years after trying a number of other drinks that just didn't cut it. My fav flavor is grape - a nice subtle flavor. Something I've noticed with all of the flavors is the slight tartness due to the high levels of vitamin C - I don't mind it, but I do find it to be unique in a sports drink. I always mix at full strength and consume about 2 scoops/hour. Since switching to EFS, I've enjoyed the benefits of well fueled training sessions, but I also find that I'm less depleted after them making recovering easier and setting me up well for my next training session.

    tastes good, mixes well
    October 13, 2014
    EFS mixes very well at high concentrations, so it works great when I need to get a few more calories through fluids instead of gels. Also has one of the highest electrolyte levels I could find.

    did my first ironman with this stuff
    October 23, 2012
    I trained for my first ironman with this and raced with it as well. My biggest fear was GI issues. I have to say, I stayed super hydrated with this and felt great throughout the race. I looked like a million bucks at the end of the race as I watched so many going down with cramps and dehydration issues.

    Does the job, tastes good
    August 11, 2011
    I have a sensitive stomach; there is no getting around it. I have tried numerous hydration products and have not been happy. This one so far has served me well. I prefer citrus flavors and have liked the lemon-lime best. When it gets warm it is not gross tasting, that is a big deal to me. I am heavy, salty sweater and this product has helped to keep me hydrated. The First Endurance Company does a good job in making sure there products live up to their testing. The EFS drink has a good job in helping me avoid cramping and stay hydrated. Also the claim of mixing easy stands true.
    Easy on your stomach, Easy To Use, Mixes easy, Tastes good when warm
    Best Uses:
    Endurance Training, General Fitness, Running, Cycling
